Abstract
An oxygen cell capable of minimizing overvoltage increases is provided. An oxygen cell 1 comprises a positive electrode 2 that uses oxygen as an active material, a negative electrode 3 that uses metallic lithium as an active material, and an electrolyte layer 4 sandwiched between the positive electrode 2 and the negative electrode 3, wherein the positive electrode 2 contains a lithium compound.
Claims5
An oxygen cell comprising:
- a positive electrode to which oxygen is applied as an active material;
- a negative electrode to which metallic lithium is applied as an active material;
- and
- an electrolyte layer sandwiched between the positive electrode and the negative electrode,
- wherein the positive electrode, the negative electrode and the electrolyte layer are disposed in a sealed case, and the positive electrode contains a lithium compound and an oxygen storage material, and
- wherein the oxygen storage material comprises one composite metal oxide selected from a group consisting of YMnO3, Y1-xAgxMn1-yAyO3 (where A is Ru or Ti, 1>x>0, and 1>y>0), and Y1-xAgxMn1-yTiyO3 containing ZrO2 (where 1>x>0, and 1>y>0).
